摘要
电力载波通信是以现有的电力电缆为载体实现数据交换的一种通信方式。随着网络通信技术的发展,这种由于不需要铺设通信专线,且可以有效降低系统的运行成本的通信技术开始在工业自动控制领域获得应用。针对现有铁路道岔液压转辙机油压检测方法存在的不足,设计了一种基于PL3201电力线载波扩频通信的铁路道岔转辙机液压检测系统,实现了对铁路液压转辙机健康状况的实时在线监测。
Power line carrier communication is a kind of communication that takes the power line as the media of data exchange. With the development of network communication, this technology has been widely used in automatic control. It can reduce the cost of the system by saving the expenses of setting up a special line. Due to the absent of a sufficient way to test the pressure of switch machine, a system for monitoring the state online based on PL3201 chips is presented.
